VNT - CAN logging does not work

Hi, I’m trying to log real CAN signals from a car. If I use the Vehicle CAN Bus Monitor everything works perfectly fine (I can see different rpm signals of the engine based on a .dbc file). If I use the Simulink CAN Log and CAN Configuration blocks, the value tables do not contain the data I need. I installed the Peak System USB driver and the Matlab Add-on.

What’s my problem?

Thanks for your help! Stefan
